SPEED-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 622,011, dated March 28, 1899. Application filed February 11,1899'. Serial No. r.105,302. (No model.)

To @ZZ whom t may concern:

Be it known that I, JOSEF NATTERER, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Speed Regulatorsfor Music-Boxes, of which the following is a specification.

This invention relates to'speed-regulators for music-boxes, the object of the same being to produce a simple, reliable, and durable speed-regulator for the purpose of controlling the movements of the motor, so that a piece of music can be played slow or fast, as desired.

The invention consists of a suitably-supported regulator shaft connected with the motor and supported in any suitable manner, a guide-plate arranged on the shaft, vanes guided inwardly or outwardly relatively to each other upon said guide-plate, a vane-controller sliding on said shaft, means for actuating said controller, and suitable means of connection between said controller and the vanes, whereby the same are moved so as to offer more or less resistance to the air, as will be hereinafter clearly described and then particularly claimed.

In the accompanying drawings, Figure 1 is a front elevation of my improved speed-regulator for music boxes, showing the vanes in their innermost position, so as to oer the least resistance to the air. Fig. 2 is a section on the line 2 2 of Fig. l. Fig. 3 is a similar view to Fig. l, parts broken away, showing the vanes in their outermost position for offering the greatest resistance to the air. Fig. 4 is an enlarged section on the line 4 4, Fig. 3. Fig. 5 is an enlarged section on the line 5 5, Fig. 3 5 and Fig. 6 is a detail perspective view of the guide-plate for the vanes.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A indicates the bracket-frame for supporting the working parts of the speed-regulator and which is at-y tached in proper position in the music-box for enabling the regulator to control the speed of the motor.

B indicates the'motor-shaft, and B a wormwheel mounted on said shaft, which shaft turns in a bearing furnished by the plate B2, fixed to the bracket.

Journaled at one end in a suitable bearing in one arm A' of the bracket-frame A and at the other end in aplate or support A2, IiXed to the bracket, is a shaft C, which is provided with a Worm C', that meshes with the teeth of the worm-wheel B.

Held on the shaft C by friction or in any other suitable manner is the guide-plate D, said plate being provided with wings D D2, which, as shown clearly in Figs. 5 and 6, are offset relatively to each other or, in other words,l lie in parallel planes. The wings D D2 are connected together by means of curved connecting portions d d', which are respectively curved in opposite directions, so as to form a sort of hub which can slip over the shaft. The guide-plate is formed by slitting the same at the central portion and then opening ont the connecting portions cl CZ in oppovsite directions, so that the wings of the guideplate are offset. In this way by striking up the connecting portions d cl/ from the body of the plate the same are enabled to have a certain spring action, so that the partsd d will have a frictional contact with the shaft and hold the guide-plate in position. Upon the opposite sides of the wings D D2 of the guideplate guide-anges d2 d2 are formed. These iianges are produced by bending the edges of the wings inwardly, as shown in Fig. 6. Guided upon the opposite surfaces of the wings D D2 are vanes E, the inner ends of said vanes being received within said iianges and the outer ends of the same being bent or curved outwardlyin opposite directions. The vanes E can be moved inwardly or outwardly relatively to each other along the opposite surfaces of the guide-plate by suitable means, presently to be described, the movements of the vanes being limited by means of headed studs or pins e thereon, which pass through slot-s e', formed in both wings of the guideplate D.

F indicates a vane-controller, which is provided with a hub F for guiding the controller upon the shaft C. The hub of the controller is arranged within the open middle portion d4 of the guide-plate, while the opposite ends of the controller are provided with converging slots f, which receive the studs or pins e. When the controller is slid along the shaft C, the slotted ends f,in connection with the studs IOO e, produce the sliding movement and adjustment of the vanes of the regulator.

f' f indicate annular flanges formed on the hub F, and into the groove or space formed between the lian ges a finger g on the innerend of an actuating-pin G, guided in the arm A of the bracket, projects, so that the reciprocation of the actuating-pin produces a corresponding movement of the vane-controller. The actuating-pin is provided at its Outer end with a laterally-projecting stud g, that is received by an oblique slot h in the inner end of a slide or push-piece H, which is guided in its inward and outward movements by means of a guide-piu I, mounted on the bracket and extending into a longitudinal slot i' in said slide.

The parts of the regulator can be readily detached for repair, inasmuch as the ends of the regulator-shaftl are formed with pivots C2, one of which can be fitted in the bearing furnished in the arm A, while the other end of the same can be fitted in the bearing furnished by the plate A2, which, being of spring metal, can be sprung away from the shaft, so that the latter can be removed. The bearing in the arm A' is furnished by means of a bushing 7.,', fitted in an opening in the end of the arm A, a bearing-piece 7d, and a closingplug 7.22 on the end of the clip K, which is fastened in any suitable manner, as by means of a screw 7a3, to the arm A. 'Ihis construction of bearing permits the parts of the same to be renewed and enables an easy running of the speed-regulator. Y

The parts of the regulator can be readily oiled when necessary, aud they are all connected so that they can easily work together with no binding action.

In the position shown in Fig. l the speed of the motor is normal, as it isvnot influenced except by the customary position of the vanes. To reduce and regulate the speed of the motor of the music-box, an inwardly-reciprocating motion is imparted by hand to the slide II, so that the inclined walls of the slot 7L will impart an inward movement to the actuatingpin G, thereby moving the vane-controller inwardly and causing, by reason of the pinand-slot connection cf, the outward movement of the vanes E upon their 4guide-plate. In Fig. 3 the extreme limit of outward movement which can be imparted to the vanes is shown, and it is evident that according to the different distances to which the vanes are adjusted from each other the speed of the m0- tor will be regulated and varied.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a speed-regulator for music-boxes, the combination,withabracket-frame,andashaft suitably jourualed therein and adapted to be geared with the motor, of a guide-plate mounted on the shaft and provided with outwardlyextending wings, vanes guided upon said guide-plates, a longitudinally-movable vanccontroller mounted on the shaft, suitable means of connection between the vane-controller and the vanes, and means for adjusting said vane-controller and vanes, substantially as set forth.
